This page covers two distinct but related packaging topics: (1) the EU rules on materials and articles that come into contact with food (food-contact materials, or FCM), relevant to the packaging of algal food products; and (2) the emerging use of algae-derived biopolymers and materials in food packaging itself.

Regulation (EC) No 1935/2004 of the European Parliament and of the Council of 27 October 2004 on materials and articles intended to come into contact with food, OJ L 338, 13.11.2004, p. 4. EUR-Lex

Relevance to algae: This framework Regulation applies to all materials and articles (packaging, containers, equipment) that come into contact with food, including algal food products. It establishes the overarching principle that food-contact materials must not:

• transfer their constituents to food in quantities that could endanger human health;
• bring about an unacceptable change in the food's composition;
• bring about a deterioration in the organoleptic characteristics of the food.

The Regulation establishes the general framework and authorises the Commission to adopt specific measures for particular FCM materials. The most commercially significant specific measure is for plastics (see below). The framework applies equally to packaging for algae as for any other food; there are no algae-specific derogations or special rules at this level.

Commission Regulation (EU) No 10/2011 of 14 January 2011 on plastic materials and articles intended to come into contact with food, OJ L 12, 15.1.2011, p. 1. EURlex

Commission Directive No 2007/19/EC of 2 April 2007 relating to plastic materials and articles intended to come into contact with food EURlex

Relevance to algae: The most detailed and commercially important specific measure under Regulation (EC) No 1935/2004 covers plastic packaging. It establishes a positive list of substances that may be used in the manufacture of plastic FCMs, migration limits for specific substances and for overall migration, and testing requirements. Producers of packaged algal food products who use plastic packaging (pouches, films, rigid containers, caps and seals) must ensure that their packaging materials comply with this Regulation, typically demonstrated by a declaration of compliance (DoC) from the packaging supplier.

The DoC chain is important: the algae producer needs to obtain a DoC from their packaging material supplier, and should pass on a DoC to any food business customer receiving their product packaged. This is a standard requirement for food businesses but is sometimes overlooked by smaller algae producers.

By analogy, the same regulation is relevant also for the materials used in algae production (pond liners, PBR tubes, filters, dryers, …). In those circumstances the chemical resistance is also important as growth media is usually quite corrosive. A rule of thumb here is to use materials intended for drinking water tanks. Some testing under real conditions is always advisable.

Specific EU harmonised measures do not yet exist for all FCM types; paper and board, for example, do not have a harmonised EU FCM regulation and are governed by member state rules (with Germany and France having particularly detailed national systems that are widely referenced across the sector). Algae producers using non-plastic packaging should verify applicable national rules in their primary markets.

Regulation (EU) 2025/40 of the European Parliament and of the Council on packaging and packaging waste, OJ L, 22.1.2025 (the “Packaging Regulation”, replacing Directive 94/62/EC) EURlex

Relevance to algae: This recently adopted Regulation establishes EU-wide requirements for packaging design, recyclability, recycled content targets, and restrictions on unnecessary packaging. Key requirements relevant to algae producers:

• Recyclability — packaging must be recyclable as of 2030 at the latest (with the timeline and methodology for assessing recyclability to be defined by implementing measures).
• Minimum recycled content — targets for plastic packaging increase progressively from 2030.
• Restriction on unnecessary packaging — specific restrictions on packaging formats deemed wasteful (overpackaging, unnecessary secondary packaging) that may affect how some single-serving or sample-sized algae products are packaged.
• Extended producer responsibility — producers placing packaged food on the market are subject to EPR schemes in each member state; the Regulation harmonises some aspects but implementation remains national.

This Regulation is recent and its full implementing measures are still being developed; producers should monitor progress closely, particularly on recyclability definitions which will affect choice of packaging material.

A growing area of commercial and research interest is the use of algae-derived polymers in food packaging itself. Principal materials of interest include:

• Agar and carrageenan-based films and coatings — red seaweed polysaccharides have been studied and some are in commercial development as edible films, oxygen barriers and surface coatings for food packaging.
• Alginate-based materials — brown seaweed alginates can be formed into films and used as edible coatings; some commercial applications exist in the food industry.
• PHA (polyhydroxyalkanoates) from algal biomass — microalgae can be used as a feedstock for producing biodegradable polymers; this is a more distant commercial development but is within the research and pilot-scale landscape.

For an algae-derived material to be used in food contact applications, it must comply with Regulation (EC) No 1935/2004, which means:

• If it is a plastic material, any novel monomer or additive used in its production must be on the positive list in Regulation (EU) No 10/2011 (or a specific authorisation must be obtained for its inclusion).
• If it is a material category for which no EU harmonised specific measure exists (as is currently the case for many biopolymers), the general safety requirements of the framework Regulation apply, and in some member states additional national requirements must be met.

The use of algae-derived packaging materials thus presents a dual compliance question: the producing company must satisfy FCM safety requirements for the material, while the end-user (food producer) must obtain a DoC and ensure the material performs within the migration limits for their specific food product and storage conditions.

The general food information requirements applicable to packaged algal food products are covered in Food Labelling, including mandatory particulars under Regulation (EU) No 1169/2011 and the additional aquaculture-specific labelling requirements under the CMO Regulation.

• Always obtain a declaration of compliance from your packaging supplier — this is a legal requirement under Regulation (EC) No 1935/2004 and Regulation (EU) No 10/2011, and is also necessary for your own due diligence chain.
• For non-plastic packaging, check national rules in your key markets — Germany, France and other member states have specific national FCM rules where EU harmonised measures do not exist.
• Monitor the Packaging Regulation implementing measures — recyclability requirements and minimum recycled content targets will affect packaging material choices from 2030 onwards, and early planning is advisable.
• Algae-derived packaging materials are commercially interesting but carry regulatory development risk — before committing to an algae-based packaging solution that is not yet clearly covered by an existing EU specific measure, obtain a legal assessment of the FCM compliance pathway.
